cu LTIVATOR.

SPECIFICATION forming part of Letters Patent No. 506,171, dated October3, 1893.

Application filed July 28, 1893. Serial No- 481,761. (No model.)

To all whom it may concern:

Be it known that], EBENEZERB. FARNS- WORTH, a citizen of the UnitedStates, residing at Oakfield in the county of Genesee and State of NewYork, have invented certain new and usefullmprovements in Cultivators;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which.

it appertains to make and use the same, reference being bad to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to certain new and useful improvements incultivators of that class in which the axle is broken or rather in whichthe wheels are carried by stub axles which are mounted for pivotal orswivel movement.

It has for its objects among others to provide a simple and cheapimproved construction of this character by which the cultivator shall beheld in a straight-forward position and when turned by pressure of thefoot of the operator from this position shall be automaticaily returnedthereto as soon as the said pressure is removed therefrom.

As will be hereinafter clearly seen the inner ends of the stub axles areconnected by a cross piece which is pivotally connected thereto andwhich is acted upon by a spring which may be a flat or a coiled spring,the other end of which is attached to some fixed part of the frame.

My improvement can be readily applied to cultivators now in use withsmall cost and but little change in the construction thereof.

Referring now to the details of the drawings by letter, A designates thestub axles upon which the wheels are designed to be carried, the stubaxles and wheels being of any well known or approved forms ofconstruction.

B is the frame of the cultivator, also of any suitable form ofconstruction, and atits rear end connected by the cross piece 0 which isextended beyond the side bars of the frame and to the extended ends aresecured the bearings D for the vertical pintles or pivots d of the stubaxles, which pintles are held therein in any suitable manner so as toallow the axles to move freelyin either direction. Each of the stubaxles has either secured thereto or integral therewith the centrallyprojecting and upward and forwardly extending preferably curved arms Fthe upper ends of which terminate above the frame and are pivotallyconnected by the cross bar or piece G which rides over the side bars ofthe frame of the cultivator as seen in Fig. 2.

H is the pole or tongue secured to the front cross bar of the frame andto the rear cross piece 0 in any suitable manner; the cross piece G isconfined between this pole or tongue and the side bars of the frame butis free to move transversely of the machine. It is to be moved by thefoot or feet of the operator by pressing thereon.

I is a spring one end of which is secured to the pole or tongue or tosome other fixed part and its rear end is arranged to act upon the crosspiece G as shown. This spring may be of any desired or suitableconstruction, but is preferably a flatspring plate or bar set upon edgeand its rear end passed loosely yet confinedly between the pins f whichare held in the cross piece G as shown. In the absence of this springthere is nothing to guide the wheels or cultivator except the feet ofthe driver but the spring furnishes a yielding hold for the wheels andyet allows the wheels to be easily turned to guide the cultivator to theright or to the left and then quickly returns it to its correct positionas soon as the pressure or weight of the feet is removed.

WVhat I claim as new ist 1. The combination with the frame and brokenaxles pivoted as described, of a bar connecting the axles, and a springsecured at between pins upon said cross bar, substan- IO tially as andfor the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
